We had 2003r2 DC that had DFS; we have upgraded the schema to 47 and put 2008 r2 DC.
I have exported the name space from 2003r2 then deleted it and decommissioned the server and removed all the server roles on it.
All the DCs we currently have are 2008r2 with schema ver 47, and DFL, FFL is 2008. however I have tried to put the name space on 2008r2 DC the enable windows server 2008 mode greyed out and also it shows that the Namespace type: Domain (Windows 2000 Server mode) ?? While we only having 2008r2 DC and the name space was deleted from 2003 dc
I used ADSI Edit try looking at the 2003 server to check the dfs there was nothing
DC=MyDOMAIN, CN=System, CN=Dfs-Configuration
Has anyone have an idea what is happening and how to fix it?
